1. Introduction Ochratoxin A (OTA) is a naturally occurring mycotoxin produced by the Aspergillus and Penicillium species that can be found as a contaminant of poultry feeds. OTA contamination can occur from cool temperate to tropical regions (Northern and Southern America, Northern and Western Europe, Africa and South Asia) [1]. Dietary contamination by OTA also poses a big risk for animal health and is a food safety concern due to the transfer of this...

For many years reactive oxygen species (ROS) production in biological systems has been considered to be detrimental. However, a pleasant face of ROS has received recently tremendous attention. Indeed, it has been proven that ROS participate in cell signalling, transcription factors regulation and vitagene activation to maintain optimal cellular redox balance and to provide an effective stress adaptation [1]. In fact, redox biology is a very rapidly developing area of modern biological...

1 INTRODUCTION During the last decades, the productivity of laying hens has improved significantly, with higher number of eggs produced over the laying cycle and higher efficiency to utilize feed nutrients. This increase in productivity implies in a change in the requirements, and consequently, these hens become more demanding in nutrients, mainly amino acids (Elliot, 2008). Optimization of protein supply by understanding the amino acid needs of these hens requires a thorough...

INTRODUCTION Dietary amino acids (AA) and crude protein (CP) have been demonstrated to affect BW, body composition, organ development, and feathering in broiler breeder pullets (Hudson et al., 2000; Ekmay, 2011; van Emous et al., 2013). Breeder pullets are fed to achieve target BW, and meeting growth objectives during the rearing phase has been related to improvements in reproductive parameters such as fertility, hatchability, and embryo mortality (Leeson and Summers, 2000;...

Botanicals represent a wide class of complex compounds that naturally contain active principles with numerous biological functions. Among them, the anti-inflammatory and antioxidant actions are of key interest to support intestinal health during stressful phases. The aim of this study was to investigate the ability of a thymol-based blend of botanicals (BOT) to protect intestinal Caco-2 cells from the damages induced by an inflammatory challenge in vitro. Caco-2 cells were differentiated on...
